Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

unless otherwise specified.

Note 3: Guaranteed by design, not subject to test.

Note 4: Integral nonlinearity is defined as the deviation of a code from

a straight line passing through the actual endpoints of the transfer

curve. The deviation is measured from the center of the quantization

band. Guaranteed by design, test correlation and 3 point transfer curve

measurement.
